Today I have upgraded my Active Directory Domain Controller to Windows 2016 Datacenter, no issue found during the upgrade and everything went smooth. My Cisco Firepower User Agent for Active Directory V2.3 was working on my old Windows 2008 Active Directory server. So I thought to install it on new Windows 2016 server and to remove old server.Therefore, I installed Cisco Firepower User Agent for Active Directory v2.3 on new Windows 2016 AD server. Installation went fine, then In Cisco Firepower User Agent for Active Directory, I added the host (New Windows 2016 AD Server). It shows status – available. In Firepower management center I added FireSight Server IP address. But after a few minutes later its state became unavailable.

Solution 1. Uninstall Microsoft updates KB3161606 and KB3161608 and prevent them from reinstalling again on your system.Solution 2. In my case above solution did not work, as I did not find above KBs on Windows 2016. Then I edited my registry keys.Edit the registry:*HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\*Add the new Key name “Diffie-Hellman“*Under the newly created Key, add the DWORD Value.*Type "ClientMinKeyBitLength" for the name of the DWORD, and then press Enter.

*Right-click ClientMinKeyBitLength, and then click Modify.In the Value data box, type "200" in Hex, and then click OK.*Restart Cisco Agent service and everything will start working again.Check authentication logs on FMC under Analysis > Users > User Activity.

Upgrade or migrate interactively using an ESXi installer ISO image on CD/DVD or USB flash drive

You can run the ESXi 6.0 installer from a CD/DVD or USB flash drive to do an interactive upgrade or migration. This method is appropriate for deployments with a small number of hosts. The installer works the same as for a fresh installation, but if you select a target disk that already contains an ESXi 5.5 installation, the installer upgrades the host to 6.0 and gives you the option to migrate some existing host settings and configuration files, and preserve the existing VMFS datastore.
Here we are going to Upgrade or migrate to ESXi 6.0 interactively using an ESXi installer ISO image on CD/DVD or USB flash drive.
So lets start,
My current version of ESXi is 5.5 as shown below,

Now turn of the ESXi 5.5 server & mount ESXi 6.0 ISO file & power on the ESXi server for upgrade,

Press F11 to accept the EULA and continue.

Select the virtual disk where you want to install, and press Enter to continue.

Select option “Upgrade ESXi, preserve VMFS datastore” as we want to retain old VMFS partition as it has our Virtual machines.

Confirm that the information on the screen is correct, then press F11 to start the installation.

When the upgrade is complete, Press Enter to reboot.

Now you can see ESXi 5.5 is upgrade to ESXi 6.0 without any data loss…
